Fraser Anning delivered an "absolutely magnificent" maiden speech by calling for a ban on Muslim immigration and invoking Nazi Germany's "final solution", according to his party leader Bob Katter.

Mr Katter, a long-serving lower house MP from far north Queensland, said the inflammatory speech was "solid gold" and Senator Anning's ideas were "everything this country should be doing".

That included the Muslim ban, a drastic reduction in Australia's migrant intake and a return to the discriminatory immigration system of the White Australia Policy, dismantled in the 1960s and '70s.

"I love it. Our phones are on fire. Ninety per cent of Australia have been waiting for someone to say it and believe it," Mr Katter said.

"Absolutely 1000 per cent I support everything he said. His speech was absolutely magnificent. It is everything his country should be doing. It was solid gold."

Senator Anning was elected on the One Nation ticket in November last year when the High Court found Malcolm Roberts was ineligible because of his dual citizenship. Senator Anning quit One Nation immediately and sat as an independent before in June joining Katter's Australian Party.

His first speech to the Senate on Tuesday evening has been widely condemned as racist by Prime Minister Malcolm Turnbull, Opposition Leader Bill Shorten and even One Nation leader Pauline Hanson, who said she was "appalled" by Senator Anning's remarks.

But Mr Katter, who has himself courted controversy with derogatory remarks about homosexuality, defended Senator Anning - including his call for a "final solution to the immigration problem".

Mr Katter claimed his senator had "absolutely no idea" the term was used in Nazi Germany under Adolf Hitler to describe the genocide of the Jewish people in Europe.

"He didn’t get to a university to know the significance of all these words," Mr Katter said. "He's smart, but he hasn't read all the history books. He doesn't know what any of this means. And nor will he spend any time finding out.

"I'm sick of you lily pad lefties coming at us on some absolutely ridiculous technicality that has nothing to do with the issues."

Mr Katter said his party was resolutely pro-Jewish and wanted to protect Jewish people in Australia from "the persecutors" being brought in from the Middle East under Australia's migration program.

He went on to say Energy and Environment Minister Josh Frydenberg - who is Jewish - "should be ashamed of himself" for being part of a government that allowed Muslim immigration.

Senator Anning has also refused to apologise or back down, telling various media outlets he had been victimised by the "thought police".
